The Electron rocket, named Still Testing, took off from Mahia, on the east coast of the North Island, at 2.45pm (local time) on Sunday and reached orbit eight minutes later.

The 17-metre carbon-fibre rocket is carrying three satellites into space -- one to take images of Earth for United States company Planet Labs, and two to capture weather and ship tracking data for Spire Global.

“Speechless. Just like that, @rocketlab reaches orbit and sets a new bar for launch by reaching orbit on just their 2nd test,” satellite-powered data company Spire tweeted.

Rocket Lab conducted its first launch last May when the firm put a rocket into space, but it did not reach orbit.

Although New Zealand-founded, Rocket Lab lists itself as an American company with headquarters at a wholly-owned New Zealand subsidiary.
